The direct modification of an organism's genome by inserting a gene from another organism (or a modified gene) to give it a new or altered characteristic. The resulting organism is called a genetically modified (GM) organism.

How is insulin produced using genetic engineering?

The human insulin gene is inserted into bacterial plasmids. The bacteria are grown in large fermenters and produce human insulin protein. This insulin is then purified for use by diabetics. Before this, pig or cow insulin (slightly different) was used.
